/* ドパチャイポ — visual skin.
 *
 * Cards are chai-po.com's: a solid suit-coloured tile with one big white rank
 * (spade grey / heart red / diamond blue / club green / joker purple, jester mark for JOKER).
 * Everything around them is VALORANT-flavoured tactical UI: near-black ground, hairline
 * geometry, cut corners, uppercase condensed type, red accent.
 *
 * Type: Anton for latin and numerals, Noto Sans JP (gothic) for Japanese. Anton has no kana
 * or kanji, so Japanese automatically falls through to the gothic stack.
